Objective: Prior research suggests that effort and reward are central to cognitive fatigue. To better understand the influence of reward on cognitive fatigue, this study examined the effect of reward type and frequency on cognitive fatigue.
Participants And Methods: In an online between-subjects study, 400 participants completed a computerized switching task and were randomly sorted into one of the five possible groups based on reward condition: [1] infrequent money, [2] frequent money, [3] infrequent performance-feedback, [4] frequent performance feedback, and [5] no-reward.
Article Synopsis
- This study focused on understanding how common diagnostic uncertainty is when critically ill children are admitted to Pediatric Intensive Care Units (PICUs) and what factors contribute to it.
- Researchers reviewed medical records from 882 pediatric patients across four hospitals to assess the presence of diagnostic uncertainty at admission and how it changed by the time of discharge.
- Key findings indicated that 25.9% of patients showed diagnostic uncertainty upon PICU admission, with significant factors being the time of admission, illness severity, atypical symptoms, and discrepancies in diagnoses between different healthcare providers.
The perennial grass Thinopyrum intermedium (intermediate wheatgrass [IWG]) is being domesticated as a food crop. With a deep root system and high biomass, IWG can help reduce soil and water erosion and limit nutrient runoff. As a novel grain crop undergoing domestication, IWG lags in yield, seed size, and other agronomic traits compared to annual grains.

Here, we elucidate the underlying physiological controls of H/H fractionation in algal lipids by systematically manipulating temperature, light, and CO(aq) in continuous cultures of the haptophyte . We analyze the hydrogen isotope fractionation in alkenones (α), a class of acyl lipids specific to this species and other haptophyte algae.

While distinct frontoparietal networks have been associated with specific cognitive control functions such as switching, inhibition, and working memory updating functions, there have been few basic tests of the role of these networks at the individual level.
Methods: To examine the role of cognitive control at the individual level, we conducted a within-subject excitatory transcranial magnetic stimulation (TMS) study in 19 healthy individuals that targeted intrinsic ("resting") frontoparietal networks.
